From clean air to a toxic chamber: Indian cities with the lowest and highest AQI levels, as per CBCP's new report
India’s air on 15 December 2025 told two very different stories. In some corners of the country, the sky was clear and the Air Quality Index sat comfortably in the “good” range. In others, especially around Delhi and the Indo‑Gangetic belt, the air was thick with fine particles, pushing into “very poor” and even “severe” territory according to the Central Pollution Control Board’s (CPCB) official 4 pm bulletin for that day.
